Ultra-thin pneumatic ball valve by the combination of pneumatic double piston rack and pinion actuator and ultra-short flange distance ball valve. Pneumatic piston actuator is divided into spring type and no spring type two. When the valve is fully opened or closed, it is required to be equipped with a spring type (by the recovery of tension by the spring). When the valve is required to maintain position, it is equipped with no spring type. It is mainly composed of cylinder block, spring, piston, piston rod, front and rear cylinder head, rack, output shaft and other components. For two position switch valve, need to match solenoid valve and travel switch; For proportional control valve, need to match positioner.
